NEW JERSEY KNITTING MACHINE Orizinal application filed March 19, 1926,

Serial No. 96,049. Divided and this application filed April as, 1930. Serial No. 447,094.

This application is a division of application Serial No. 352,503, filed April 4, 1929 and of application Serial No. 96,049, filed March 19, 1926 now August 6, 1929.

This invention relates to a pattern mechanism of extreme flexibility in the setting up of designs for knitting machines. The device is capable of use for the purpose of controlling the needles of the machine and any other instrumentalities of the machine upon which a control action is desired to vary the fabric knit b the machine. A more complete setting orth of the advantages of this device is contained in the above mentioned applications.

Referring to the accompanying drawings which are made a art hereof and on which similar reference c aracters indicate similar p Fig. 1 is a cross sectionof the trick wheel on line 1-1 of Fig. 2,

Fig. 2 is a cross section of the trick wheel on line 2-2 of Fig. 1,

Fig. 3 is a side view of a single trick, and

Fig. 4 is an edge view thereof.

In the drawings the cylindrical trick wheel is indicated at 5 having the walls 6 and the hollow central hub 7 connected to the walls 6' the web 8. Slots 9 are cut or otherwise formed in the wall 6 to provide a means for placing interchangeable tricks 10 in position on the wheel the slots being preferably radial with respect to the axis of the wheel, as here shown. In a preferred embodiment of the invention the tricks 10 are secured around the wheel in the slots thereof as shown in Fig. 1 thou h obviously they may be of other form and field in place in other ways. The tricks are held in osition on the wheel by means of the spring and 11 which is placed on the wheel to engage the curved slots 12 of the tricks and to engage in a circumferential roove between the two annular ribs 13 adacent the top of the trick wheel 5 and integral therewith.

Each trick may comprise an elongated strip like body member 14 preferably punched out of any suitable material; e. g. sheet metal of suitable strength such as steel Patent No. 1,722,989

and provided with a plurality of frangible butts or projections 15 arranged lengthwise thereof, the butts being here shown as extendmg from an edge of the member 14 and lying in the plane of the body of said member. These butts are made sufficiently strong to provide the desired operation in the ma chine and yet are of such construction that the butts may be broken out as desired as shown at 18 in Fig. 2, the breaking out of the butts being done by any suitable operation which removes substantially the entire butts at once, in accordance with the desired design to be made on the instrumentalities which are controlled by means of the trick or pattern wheel element. The butts 15 are made by subjecting the trick blank having a full complement of selective operating points to an operation which makes saw cuts 19 crosswise of the trick, the butts then being between successive saw cuts and substantially identical and substantially equally spaced. As another instance of a pattern element reference is had to the pressers or sub-jacks disclosed in Ames application 25,915, filed April 25, 1925 in the U. S. Patent Office, where the pressers lie in the needle slots of a knitting machine said pressers being made in the same way as the tricks. The active ortion of each butt, as clearly set forth in t e applications and atents above referred to, is the outer end ace of a butt, which bears against a coperating device or devices. The upper end of the trick is beveled at 20 so that the tricks can be readily inserted beneath the spring band 11. At the bottom of the trick there is an extra wide butt 16 and the entire series of tricks by means of the butts 16 present a ratchet by means of which a pawl may index the trick wheel about a vertical axis inside the central opening 7, as more fully explained in the patent and application above referred to.

It will be seen that there is provided a pattern member upon which a pattern may be set up in an inexpensive manner and in an extremely short length of time. Furthermore the control parts of the wheel are strong and are very efficient in operation. Inasmuch as there are numerous parts and instrumentalities u on a knitting machine which are controlles by means of pattern mechanism in order to cause the machine to knit a desired design, it will be seen that there is provided an extremely eflicient pattern element for such use at various places on a knitting machine. For example a presser or selector or sub-jack with frangible butts may cooperate with needle-controlling jacks as shown in Patent No. 1,722,989, and various other possibilities of use of the trick wheel and the strip-like elements with frangible butts will occur to those skilled in the art,as will also numerous variations in the structure of such parts. For the reasons stated the invention is not confined to the structure shown and described, nor to the specific uses illustrated d described, but only as indicated in the applended claims.

aving thus fully described the said invention what is claimed as new and desired to be secured by Letter Patent is:

3. A pattern wheel having longitudinal grooves about its periphery, a circumferential groove intersecting them, a sprin ring in said circumferential groove, and di erentiated strip-like elements in said longitudinal grooves each with radiall extending frangile butts havin active aces at their outer ends said strip-like elements being beveled at their upper ends so as to pass easily under said spring ring.

4. A pattern wheel for knitting machines said wheel having intentionally frangible butts of frangible material extending outwardly therefrom and arranged in rows circumferentially of the wheel, substantially as set forth.

5. A pattern wheel for knitting machines said wheel having intentionally frangible butts of frangible material extending outwardly therefrom and arranged in rows circumferentially of the wheel and longitudinallyof the wheel, substantially as set forth.
